@Snakelimit - Hope you feel better soon
@T6Norfolk - What control unit do you have for your seats, is it 4M6959760E too?
As I need the seats to be ready tomorrow, I couldn’t wait to sort the controller unit out and have stripped out all the cables, thankfully it seems straight forward as all the motors (and there looks to be 5 !) have the thickest cables and are closely paired/colour wise, so I can relatively easily isolated and control each motor.
